Description
Technical field
Interior (between the tissue) X-ray therapy that the present invention relates to a kind of tumor is used instrument, particularly a kind of implantation device of going into miniature radioactive source at the tumor tissues inter-planting.
Background technology
Radiation treatment is as one of three big conventional meanses (operation, chemotherapy, X-ray therapy) of oncotherapy, in the treatment malignant tumor, prolong on patient's life and play important effect.
Because the current diagnosis technology limitation still can not be accomplished early discovery, early diagnosis fully, when going to a doctor, many patients just entered the middle and advanced stage of cancer, lost the chance of surgical radical treatment.Therefore adopt radiotherapy just to become one of requisite treatment means clinically.There is 70% tumor patient need carry out radiotherapy clinically approximately in the different phase of its treatment.
Because traditional outer X-ray therapy all can't be kept apart normal structure and tumor tissues; therefore in therapeutic process, can cause damage to normal tissue, organ; also can tumor can not be effected a radical cure completely owing to giving less than enough therapeutic doses for the protection normal structure.
In recent years, the man-made isotope that many half-life are short, irradiation distance is near, radiant is low is manufactured in succession come out and be applied to clinical, as
125I,
198Au,
103Pa etc. make the imagination of carrying out the radiation treatment of Wicresoft at the tumor tissues part become possibility, between radioactive particle tissue closely transplanting to treat the tumor technology be exactly one of them.This technology is to adopt low-yield, more short-decayed radioactive sealed source microgranule, through Computerized three-dimensional treatment planning systems accurate Calculation, adopts special equipment that it is implanted in the tumor body, is subjected to invade tissues and subclinical kitchen range with interventional method or in art.Lasting decay by mini-radioactive resource; tumor tissues is carried out the persistence low dose exposure; normal structure around can protecting to greatest extent; prevent the damage of responsive organ; therapeutic domain and treatment indication have been enlarged; controlled simultaneously that the tumor cell that is in resting stage is activated and the process that doubles, the deficiency that the peripheral damage that has remedied external exposure is big, oncocyte resting stage can't be effectively eliminated in the discontinuity irradiation has played positive effect to preventing the diffusion of postoperative local recurrence and tumor.Since adopt the implantation instrument of metal shell to implant by modern less invasive techniques, little to patient trauma, effectively stoped operating process to executing patient's radiation simultaneously.
The tumor tissues inter-planting of Shi Yonging was gone into the implantation device of miniature radioactive source in the past, was a kind of storage warehouse and (for example: Chinese patent ZL00259567.2) implant miniature radiation source implantation equipment that the storehouse is integrated.
In the implantation device in the past, it is incorporated storing the storage warehouse of radioactive source and the implantation storehouse that implant procedure is used.A kind of form is exactly that so-called fiveshooter formula (rotating disc type) stores the implantation storehouse, its warehouse is a disc-shape up and down, upper lower burrs respectively has corresponding grooves, be used for storage dimensions less (being about long 4.5mm, diameter 0.8mm) radioactive source in advance, dish can pivot, turn to assigned address together with radioactive source, implant the hollow needle of going back handlebar radioactive source implant into body that the storehouse links in this position and storage, push pushing pin in the tissue that to implant radioactive source then.When radioactive source forwards assigned address to and above-mentioned hollow needle, push pin at same position, be convenient to push pin, by hollow needle radioactive source is pushed human body.This implantation device has solved the problem of continuous input radioactive source, but still has several shortcomings:
